Unlike many traditional European and New World vegetables, many of the Asian type mature extremely quickly, and once ready to harvest must be picked within a day or so. Small regular sowings are required. For detailed cultural requirements we suggest reading 'Asian Herbs and Vegetables', available from our book section.
Pak Choi (Bok Choy) and Chinese Cabbage (Wong Bok) are best sown in summer and autumn in cold areas, July to March in warm areas and all year in tropics. Sow the seed where the crop is to be grown, watering and feeding generously.
